Commercial Scale Carbonization Of Briquetted Tropical Wood Sawdust.

Abstract

This paper outlines a commercial scale carbonization system that rapidly carbonizes briquetted sawdust from tropical wood species at 850° - 875°C. The various issues involved in the carbonization process and the steps taken to overcome problems encountered are discussed. To date the plant is able to produce briquetted charcoal for export. The qualities of the product are as follows: Moisture content 5.0 - 9.5%, Volatile Matter 6.3 - 9.0%, Ash 1.1 - 2.5%, Fixed Carbon 82 - 92%, Calorific Value 7200 - 8500 kcal/kg.
